Circular Quorum Systems for Write Dominant Data Replication Protocols under Serial Isolation Using Quorum Consensus Approach
Vinit Kumar, Ajay Agarwal · Procedia Computer Science · 2015
In distributed systems, we replicate data for the purpose of increasing availability and performance. If any application requires serial isolation and have the dominance of write operations can effectively use quorum consensus approach. In such a scenario, quorum consensus protocol that uses quorum systems should have smaller write quorums and good availability. In order to meet these requirements, we propose new Circular quorum systems, more suitable for data replication in write dominant scenario. These proposed quorum systems generalize the existing Crumbling-wall and Torus quorum systems.
